Specification. of Letters Patent.

Application filed October 25, 1911. I Serial N 0. 656,743.

To all whom it may concern:

Be itknown that we, AUeUsTV. BAYER and GIDEON P: Brown, citizens of theUnited States,-'residing, respectively, at St. Louis, and Chicago, inthe county of Cook and State of Illinois, have invented certain new anduseful Improvements in Boiler-Cleaners, of which the following is afull, clear, and exact description, to the accompanying forming apar-thereof; I

Our invention has relation to improve ments in boiler cleaners; and itconsists in the novel details of construction more fully set forth inthe specification and pointed out in theclaims,

In the drawings, Figure 1 is a side elevation of a boiler, with partsbroken-away,

showing our invention applied thereto;

on the zig-zag line 2-2 .of Fig. 1, of one end of the boiler-furnace andboiler; Fig. 3 is an enlarged vertical cross-section on theline 3-3 ofFig. 1; and Fig. 4 is an enlarged elevational view of a portion of thecleaning attachment, showing the riser, the rock-shaft, and intermediateconnections.

The present1invention is an improvement on the boiler cleaner formingthe subjectmatter of U. S. Letters Patent numbered 978,830, issued toLeo J no. Bayer under date of December.20,1910; and while contem--plating the several objects and possessing the various advantagesidentified with the patented device, the present improvement affords amore varied and more satisfactory COlIbIOl of the spray nozzles by whichthe cleaning'jet is projected between the tubes of the boiler operatedon.

The present improvement permits the installation of a fixed verticalriser or steam pipe, thus restricting the movable portions of the deviceto the nozzles and the parts by which they are directly controlled, thead justmentof the nozzles to'the dip of the boiler tubes being acomparatively easy matter and readily acquired by the skilled mechanic.

The advantages of the improvement will be fully apparent from a detaileddescription of the invention which is as follows Referring to thedrawings, F' represents the furnace (the walls being broken away inparts) of a well known ty e of water-tube boiler, S the shell of theboiler, Tthe waterleading from the steam space of The head 8 of anynozzle 7 tubes thereof, the water-tube section being divided oil intoindependent sections by the bathe-plates a, the general draft beingrear- Ward and upward from the fire-box F. Disposed along-one of theside walls of the furnace opposite each section or division between andon either side of, the baffle plates are vertical openings 0, taperingfrom opposite ends to a line within the furnace wall,

aperforated 'or transversely slotted plate P being set'in'the brick workat the meeting of the converging faces of said opening, theslot's's'being availed of for the passage therethrough of theoscillating nozzles as presently to be seen. The top and bottom of theouter'porti'cns of each opening '0 are provided with a shoe or casting1, between which is rigidly mounted a steam pipe or riser 2, each riserbeing tapped at the bottom by an elbow valve-casing 3, equipped with avalve V, the bottom of each elbow being connected by a pipe m with thebottom horizontal branch of a general steanrsupply pipe 4, the boilershell.

Distributed along the walls of each riser 2, and of a numbercorresponding to the number of spaces between the tubes T, disposed inany given plane between the headers H connecting the tubes, (and ifdesirable above the top and below the bottom set of'" tubes) are elbowsor branches 5, the inner arms or legs of the branches terminating inclose proximity to the plate P and opposite a slot 8 thereof, saidterminal being provided with a hollow swivel joint (5 of any approvedpattern known to the art, the axis of rotation of the movable uppersection of said joint being disposed at right angles to the planes ofdisposition of the boiler tubes T. From the movable o rotatable memberof this joint there-leads inwardly through the slot 8 of the plate I, anozzle 7 terminating in a spray-head 8, the slotted, plate 1, nozzle 7and head 8 being substantially the same as described inthe Patent978,830 aforesaid.

is thus in position to sweep (with any oscillation of the joint andnozzle carried thereby) in a plane disposed in the space between any setof tubes, the same as in the patent aforesaid.

The means for in'i parting oscillation to the nozzles 7 may be describedas follows:- Mounted rotatably between the castings l, l, at aconvenient point removed from the riser outwardly from the movab e theouter. end of which the adjacent end of a section or division into whichi The engineer by would be correspondingly less;

2 is a vertical rock-shaft or rocker-bar 9, the bottom of which isprovided with an operating handle or lever 10 set so as to be accordedsufiicient play between the outer converging sides of the wall openin O.Extending section of the joint 6, and in substantial continuation of thenozzle 7 is an arm or extension-11 (the same terminating a slightdistance forward of the angle or corner of the elbow 5), to is pivotallycoupled link 12 whose opposite end'is loosely connected to a slotted arm13 rigidly carried by the rock-shaft 9. There is thus a link connectionbetween the shaft 9 and the end of each nozzle arm 11.

The operation will be clear from the foregoing, but may be describedbriefly as follows :-By opening any valve so as to admit steam to theriser 2, the corresponding the boiler is divided by the baflles a may becleaned of soot, dirt, cinders and other accumulations. then seizing thehandle bar 10 and rocking the shaft 9back and forth will, through thelink connections described oscillate the entire series of nozzles 7identified with any opening 0, said nozzles and their terminal spray ofthe inclination of the hollow-joints 6 being caused to sweep in planes.parallel to the planes of disposition of the boiler-tubes, the cleaningfluid (steam) being thus projected into,.through and across the spacesbetween the tubes (and above and below the water-tubes if desired, byproviding additional'nozzles for that purpose).

It will be seen that we are thus-enabled to install a rigid riser 2, thelink connections from the rock-shaft ,9 and the inclination imparted tothe axis of rotation of the steam joint 6, permitting the manipulationof each nozzle 7 so that it may oscillate in a plane parallel to thegeneral planes of disposition of the several tubes T. The average dip ofthe water-tube section of a boiler is about fifteen degrees, so that theaxis of oscillation of the joint 6 (to be at right angles to such dip)would be disposed at an an le of fifteen degrees to the vertical. Wherethe tube dip was less, the angle between the vertical and the axis ofthe joint if it were more a corresponding change in the joint would benecessary,.the object sought being to maintain the axis of thesteam-joint at right angles to the planes of disposition of the boilertubes. Obviously, the cleaner is not necessarily limited to water-tubeboilers. In the present soot-blower or cleaner, therefore, it will beseen that the several nozzles are arranged one above the other in heads8, by reason vertical series, each nozzle following the di-' rection ofthe tubes and oscillating or swinging in a plane oblique to the saidvertical series arrangement of the nozzles, a fixed vertical supply pipefurnishing the cleaning fluid (steam) to the several nozzles.

I The fixed riser ing inclined to bring them substantially at rightangles to the general dip of the tubes T, it follows that these axesmust be noncoincident and at the one another.(Fig. 4). In this way wecan utilize the vertical openings 0 already present in the furnace (forthe accommodation of hand-blowing tools or lances) and still connect ournozzles to the riser 'so as to cause them toswing parallel to thegeneral planes of disposition of the inclined water-tubes.-

Having described our invention, "what we claim is: v

1. In a soot-blower for water-tube boilers having inclined tubes, afixed riser mounted opposite the sides of the tubes, a set ofpivarranged one above the other in vertical serice and oscillating aboutnon-coincident axes in the general direction of the tubes,

..thereby' following the dip of the tubes during the blowing operation.

2. In a soot-blower for water-tube boilers having inclined tubes, afixed vertical riser mounted opposite the sides of the tubes, a

set of pivoted nozzles communicating with the riser, arranged one abovethe other in vertical series and oscillating about non-coincident axesin the eneral direction of the tubes, thereby followlng the dip of thetubes during the blowing operation. a

3. In a soot-blower for water-tube boilers having inclined tubes,mounted opposite the sides of the tubes, a series of branches leadingfrom the riser hollow joints on said branches arranged one above theother in vertical series, and nozzles leading from the joints andoscillating about the axes of the several joints, said axes beingnon-coincident and substantially at right angles to the dip ofthe-water-tubes,

the dip of the whereby the nozzles follow tubes during the blowingoperation.

In testimony whereof we affix our signatures in presence of twowitnesses.
